    a.

    b.

    c.

Graph (a) is linear. Straight lines grow at a constant rate. Which function on the table is growing at a constant rate?

Since 4.4 ≠ 5.8, f(x) does not change at a constant rate. Try g(x) and h(x)

Graph (b) is increasing (the y-values are going up), but it is getting less and less steep as it increases.

Which function on the table is getting less and less steep?

Graph (c) is increasing (the y-values are going up), AND it is getting more and more steep as it increases.

Use the eTool below to create the graphs of the functions.
